Valve position checks
FLOWCONTROL
If the valve motors have become loose and the valves
have come out of position, adjust the position of the
valves using a wrench to obtain the right valve setting.
Adjust the valves according to the previous table "heat-
ing" and install with the valve motors unpowered, set to
default position (current on, control current off) and one
window on the motor displaying red.
At input control signal the valves rotate 90°.
Caution
When changing the heating/cooling mode, there
is a delay of approximately 60 seconds before
the valves change their positions.
